What is the effect of cholesterol in the cell membrane?

Biology
1 answer:
Nikitich [7]3 years ago
7 0

Answer:

a) Cholesterol moderates membrane fluidity at low and high temperatures.

Explanation:

Cholesterol is amphipathic sterol with a polar head group and non-polar steroid nucleus and hydrocarbon chain. Membranes are lipid bilayer with proteins embedded in it. An increase in temperatures makes membranes more fluid by disrupting the tight packing of non-polar tails of membrane phospholipids. At lower temperatures, tight packing of phospholipid tails makes the membranes more solid.

However, to maintain the functions of the membrane, its fluidity should be maintained within the range. Cholesterol is a moderator of membrane fluidity. Its interactions with amphipathic phospholipids make the membrane less fluid at higher temperatures and more fluid at lower temperatures.

"Discuss three factors that affect your daily food choices. For each factor with a negative outcome, suggest at least one change
professor190 [17]

Answer:

Three factors that affect my daily food choices include:

1. Taste

2. Length of time for preparation

3. Method of preparation.

Explanation:

When making choices for food, I tend to take several factors into consideration. Some of these factors include;

1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.

2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.

  • To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.

3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.

  • To turn this around, I hope to employ the help of a family member to make the process easier.
  • I also hope to process most of my ingredients and keep them ready for use so that I would not have to do a lot of processing while cooking.
